The GT-SAT GT-S1dCSS24 is a professional, programmable Unicable II/dCSS LNB with one powerful SCR output and one separate Legacy output.
The SCR/dCSS output can supply up to 24 compatible tuners through a single coaxial cable. The signal can be distributed to several receivers or rooms using Unicable-compatible splitters, making it an efficient solution where many tuners must be connected but only one coaxial cable is available.
The separate Legacy output can simultaneously supply one conventional satellite receiver or television without Unicable support. The LNB can therefore serve up to 24 Unicable tuners and one traditional receiver, providing a total capacity of up to 25 tuners or receivers.
The GT-S1dCSS24 supports EN50494, EN50494+, EN50607 and dHello. The first eight user bands work with standard EN50494 receivers. Equipment specifically supporting EN50494+ can use up to 16 user bands. Full access to all 24 user bands normally requires EN50607 or dHello support.
The LNB supports HDTV, DVB-S2 and 4K/UHD and can be programmed using the separately available GT-SAT GT-DC2 dController.

🔧 Connection and Operation
The output marked SCR is used for the Unicable/dCSS system. It can be connected directly to a compatible receiver or divided using Unicable-compatible splitters.
Every tuner connected to the SCR output must be assigned its own user band and corresponding frequency. Two tuners on the same cable system must not use the same user band simultaneously.
The output marked Legacy operates as a conventional Universal LNB output. It can supply one traditional satellite receiver or tuner using standard 13/18V and 0/22 kHz control.
A multi-tuner receiver may require several user bands. Capacity should therefore be calculated by the number of tuners, not only the number of physical receiver boxes.
📡 Capacity and Protocols
